- One batch across the order, no blending between runs
We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.
01 / The material
What this is, and what it changes in a Sri Lanka room
Timber slats on an acoustic backing. The slats are the finish and the rhythm, the backing does the absorbing. Used where the room has to look considered rather than treated.
Work reaching us from Sri Lanka is mostly hotels and resorts, apartments, offices, hospitals, schools, studios.
Concrete and block construction with hard floors, in houses and new apartment towers that share slabs.
- Slats on felt backing The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
- Slats on a cavity Backing plus an air gap behind moves absorption lower, which matters in music rooms.
- Feature wall only Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
- What it will not do A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wooden slat panels are on the main product page. This page covers what that means for a project in Sri Lanka.
02 / Data sheet
Published specification, identical wherever we ship it
We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.
- MDFStandard. Dry interiors, general commercial
- FR MDFFire rated. Public buildings and anywhere the specification calls for a class
- HDHMRMoisture resistant. Humid climates and rooms that see damp
| Substrate | MDF, FR MDF, HDF or HDHMR |
|---|---|
| Patterns | 13-3, 14-2, 28-4 and 59-5 |
| Panel sizes | 2440 x 192 mm and 2440 x 128 mm |
| Thickness | 14, 16 and 18 mm |
| Coverage | 96 sq ft per unit |
| Fire class | EN 13501-1 Class B s1 d0 on FR substrate |
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
03 / Local conditions
What we see driving Sri Lanka briefs
- Hospitality leads the market
Resorts and city hotels drive most enquiries. Guest room isolation and function room acoustics are the two recurring briefs.
- A very short sea leg
Western India to Colombo is one of the quickest runs we operate. Small and repeat orders are practical here in a way they are not for distant markets.
- Humid, coastal, monsoon
Our PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons.
- Buying direct from the plant
No importer margin between the factory and your site, and the person answering the technical question made the product.
- Assembly and performance rooms
Temples, churches and function halls are hard volumes with long decay carrying amplified speech.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate and durability
The Sri Lanka climate decides the material list
Sri Lanka is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The risk we design against here is mould, sagging fabric finishes and swelling in timber.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Getting it there
How material reaches a Sri Lanka site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Colombo, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Colombo |
| Packing | Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry. |
| Lead time | Longer than felt. Confirmed against the pattern and substrate at quote stage. |
Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Sea freight into Colombo, then a short road run to site. The short transit means even modest consignments move economically. Air freight for samples.
The same 500 sq ft minimum applies on export.
| Any specification | 500 sq ft, about 46 sq m |
|---|
One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order.
06 / Worth knowing
Four honest warnings before you buy
-
The wrong product for the problem
A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.
-
Suppliers who imply a Sri Lanka presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.
Sri Lanka: questions we are actually asked
Are these wooden slat acoustic panels made in Sri Lanka?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Sri Lanka as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Colombo. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Sri Lanka job?
Western India to Colombo is one of the quickest runs we operate. Small and repeat orders are practical here in a way they are not for distant markets. Resorts and city hotels drive most enquiries. Guest room isolation and function room acoustics are the two recurring briefs. Those two things move the build-up far more than the panel figure does.
How does the Sri Lanka climate affect this product?
Sri Lanka is warm and humid through most of the year, with a long wet season. Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them. The failure we design against here is mould, sagging fabric finishes and swelling in timber.
What is the delivery time into Sri Lanka?
ships from: Palwal, Haryana, India, arrives at: Colombo, then a short road run to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Where do wooden slat acoustic panels fail to help?
A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
Is there a minimum order, and how does it arrive?
The same 500 sq ft minimum applies on export. Any specification, 500 sq ft, about 46 sq m. One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order. Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry.
